The 83rd Academy Awards took place last night in Los Angeles, California; a number of actors from the Harry Potter films were in attendance at the ceremony and selected Oscar Parties. Composer of the soundtrack for “Deathly Hallows: Part 1″ Alexandre Desplat and Helena Bonham Carter (Bellatrix Lestrange) attended the Academy Awards as nominees for their roles in Best Picture winning “The King’s Speech”. You can find pictures of both Desplat and Bonham Carter at the Montblanc Cocktail Party and at the 83rd Annual Academy Awards here and here, respectively and find details of the winners at the bottom of this post. Sadly, “Harry Potter and the Deathly Hallows: Part 1″ did not win in either of the two categories in which it was nominated; Visual Effects went to “Inception” and Art Direction to “Alice in Wonderland”.

Bonham Carter and Ralph Fiennes attended the Vanity Fair Oscar Party, and you can find photos from that here in our galleries as well as of Gary Oldman (Sirius Black) at the 19th Annual Elton John AIDS Foundation Academy Awards Viewing Party right here in our galleries and of Jason Isaacs (Lucius Malfoy) at the previous night’s Film Independent Spirit Awards at this link in our galleries.

Secondly, keen eyed watchers will have spotted “Tiny Ball of Light”, the hilarious auto-tuned clip of a scene in “Harry Potter and the Deathly Hallows: Part 1″. The Gregory Brothers auto-tuned the clip, which aired during Sunday night’s ceremony. MTV named the auto-tuned clips as one of their top five favourite moments from the evening.

The clip has been uploaded to PopSugar, you can watch it embedded below:
